.4 Claims.

1 This invention relates to devices for attaching curtains to curtainstretchers. "Itj-is primarily within the contemplation of my inventionto provide a hand operable device which could conveniently be employedto secure a curtain to the framework of a conventional curtain stretcherwithout-the danger of injuring the hands or'fi-ngers by the nails orpins adapted to receive the curtain. And in this aspect of my inventionit is an object to provide the device with a novel type of roller memberfor progressively applying a curtain along the surfaces of a stretcherframe in such a manner as to effect a secure engagement of the curtainuponthe protruding nails or pins.

It is also an object of thiSinvention to provide the said roller memberwith a yieldable curtain .engagin -membertha-t will neither do damage tothe curtain being secured to the stretcher, nor be damaged by the pinsor nails as would be the case if rubber or other solid. .resilientmaterials .were m loy 7 ,A further object of m invention is to enablethe device to be operatively applied to curtain structures regardless ofthe spacin between the ins- Another object is to provide guiding meansfor aiding in operatively moving the device along the path of the frameto which the curtain is being attached.

And it is Within the contemplation of this invention to provide asimple, easily constructed and inexpensive device capable ofaccomplishing the functions and objects aforesaid.

Other objects, features and advantages will appear from the drawings anddescription hereinafter given.

Referring to the drawings,

Figure '1 is a'perspective view of a preferred form of my inventionbeing operatively employed to secure a curtain to a conventional curtainstretcher.

Figure 2 is a somewhat enlarged fragmentary and part sectional plan ofthe device of Fig. 1 in operative engagement with a curtain stretcher.

Figure 3 is a part elevation and part section of the device of Fig. 2taken along line 3-3.

Figure 4 is a fragmentary side view of Fig. 3.

Figure 5 is a front elevation of the coil spring employed in myinvention prior to forming into a ring as suggested by the dot-dashcurves.

Figure 6 is a bottom view of Fig. 5.

Figure 7 is a fragmentary section, like Fig. 3, of a modified form of myinvention, and

Figure 8 is a fragmentary side view of Fig. '7.

In the preferred form of -my invention illustrated, a roller It containstherein an axial shaft 1 l extending upwardly partly into the body ofthe roller, the bottomof the shaft having the-handle '|2 pivotlyattached thereto. The said shaft is rotatably mounted within the axialrecess l3 of the roller, and contains at its upper portion c.

threaded aperture M with which the threaded shank I5 of the shoulderscrew I6 is in engagement, the head I! of the screw being disposedupon-the surface |8of the upper central cavity l9 of the roller. Thearrangement is hence such that the shaft H and associated parts are-indc.-

the roller, said base comprising two spaced ears 20 with coaxialapertures 2| in registry with the aperture 22 of the handles upwardlyextending lug 23 disposed between said cars. A screw 25 extends throughsaid apertures, the head 26 thereof and the knurled nut 21 on the shankthereof engaging o-ppositesides of said ears.

Secured to the underside of the roller is a plate 28 with a centralaperture 29 throu h which the'shaft I extends, the periphery- 30 of theplate protruding beyond the roller and being upwardly curved to give theplate a cupped or dish-like appearance.

The periphery of the roller contains an annular arcuate channel 3|containing spaced transversely extending grooves 32, the top of theroller containing, preferably integral therewith, the guide disc 33having its peripheral portion 34 overhanging the channel 3|.

Disposed within the annular channel 3| is the circular spring coil 35,flanked and held against detachment from the roller by the said plate 29and disc 33. In the form shown, the terminals 36 and 31 of the springwire are in overlapping abutment, and are secured together by welding,or by any other suitable means.

In applying the coil to the roller, it is preferred first to form thecoil into a circular ring, securing together said ends 36 and 31, andthen, by stretching the coil, slipping it over the disc 33 until itsnaps into place within the channel 3|. If preferred, to preventunnecessary stretching of the coil, it could be slipped over the lowerrim 38 of the roller before the plate 28 is secured in place, andthereafter snapped into place as aforesaid. In either case, theconvolutions of the coil are so arranged that they will fit into thegrooves 3 32, whereby the coil will be held against slipping or rotatingcircumferentially within channel 3|.

In operatively employing the device, it is preferred to maintain thehandle l2 angularly with respect to the rollers axis of rotation, asshown in Fig. 1, for convenient manipulation and to keep the hand remotefrom the stretcher, the desired positioning of the handle beingaccomplished.

by manipulating nut 21 in known manner.

The guide disc 33 is, in the preferred manner of operating this device,placed against the upper surface 39 of the curtain stretcher 40containing the pins 4| arranged in a row in conven tional manner. Withthe curtain 42 applied against a selected starting point of the frame ofthe stretcher and the roller spring 35 in pressthey will. obviouslyyield when engaged by a pin, this slight displacement of a coilpreventing a bending of the pin and permitting smooth operation. Thepositioning of the coils within the grooves 32 assures uniform spacingof the convolutions, and therefore enhances the smoothness-oi action ofthe device.

the roller 43 contains a smooth annular channel 44 containing the coilpring 45. It will be noted that the outer portions 45 of the coils areflattened, thereby providing relatively greater contact surface with thecurtain as it is being applied.-

.In the above description, the invention has been disclosed merely byway of example and in '35 In the modified form shown in Figs. 7 and 8,

preferredmanner; but obviously many variations 5 and modifications maybe made therein which .will still be-comprised within its spirit. It isto not limited to any specific form or manner of a practicing same,except insofar as such limitations are specified in the appended claims.

I claim:

1. In a device for applying a curtain to a curtain stretcher, arotatably mounted roller, and a coil-spring ring mounted over the outerperiphery of the roller, the periphery of the roller containing anannular channel, the coil-spring ring being partly disposed within saidchannel, the channel containing along its circumferential extent aplurality of spaced transverse grooves within which are disposed theadjacent inner portions of the springs convolutions.

2. In a device for applying a curtain to a curtain stretcher, arotatably mounted roller, the periphery of the roller containing anannular channel, a coil spring mounted over the outer periphery of theroller and being partly disposed within the channel, and a guide disc atthe top of the roller and having a peripheral portion extendingoutwardly beyond the channel, the coil-spring ring protruding outwardlybeyond said peripheral portion of the guide disc.

3. In a device for applying a curtain to a curtain stretcher, thecombination according to,v

claim 2, further provided with a circular plate at the bottom of theroller the periphery of which underlies the said coil-spring ring.

,4. In a device for applying a curtain to a curtain stretcher, thecombination according to claim 3, the said periphery of the plate beingupwardly bent towards the coil-spring ring.
